Mute Video — Remove Audio from Video

Drop a video in, get a silent version out. Lossless — no re-encoding, no quality loss.

How it works

  1. 1

    Drop your video

    MP4, MOV, WebM, MKV, AVI, or M4V. The file stays on your device.

  2. 2

    Click Mute

    We copy the video stream untouched and skip the audio track. That means zero quality loss and it runs in seconds.

  3. 3

    Download the silent video

    Same container, same video quality, no audio.

Why use Mute video?

Lossless — we copy the video stream instead of re-encoding, so your output is bit-identical on the picture side.

Fast — no re-encoding means muting even a 1 GB video typically finishes in seconds, not minutes.

Private — everything runs in your browser, so muting a private or sensitive recording doesn't require trusting a server.

Common use cases

  • Remove background chatter from a phone recording you want to share
  • Strip copyrighted music from a clip before posting
  • Create a silent B-roll track for a video editor
  • Mute a screen recording with accidental audio
  • Prep footage for a voice-over by clearing the original audio
  • Anonymize a video by removing identifying audio

About MP4 and MP4

Muting is the lightest possible video operation: we open the container, skip the audio stream, and write the video stream through unchanged. No decode, no re-encode, no frame re-compression. The result is the same container (MP4 stays MP4, WebM stays WebM) at the same visual quality as the source. Most videos finish in a few seconds regardless of length, because we're just shuffling bytes, not re-processing them.

Frequently asked questions

Is my video uploaded to a server?
No. NoCloud Media mutes your video entirely in your browser using WebAssembly. Your file never leaves this tab.
Will the video quality change?
No. We copy the video stream without re-encoding, so the output is bit-perfect on the video side. Only the audio track is removed.
Why is it so fast?
Because there's no transcoding. FFmpeg reads the container, picks only the video packets, and writes a new file. That's mostly I/O, not CPU.
What's the maximum file size I can mute?
It depends on your browser's available memory. Files up to 500MB mute smoothly on most devices; files up to ~2GB may work on desktop browsers with enough RAM.
Which browsers are supported?
Chrome, Edge, Firefox, and Safari 15+. We require WebAssembly and SharedArrayBuffer, both standard in modern browsers.
